"If the Messenger of Allah ﷺ wanted to sleep while he was Junub, he would perform Wudu', and if he wanted to eat or drink," she said: "he would wash his hands and then eat or drink." (Using translation from Nasāʾī 257)   

كَانَ رَسُولُ اللهِ ﷺ «إِذَا أَرَادَ أَنْ يَنَامَ وَهُوَ جُنُبٌ تَوَضَّأَ وُضُوءَهُ لِلصَّلَاةِ وَإِذَا أَرَادَ أَنْ يَأْكُلَ أَوْ يَشْرَبَ غَسَلَ يَدَيْهِ وَيَأْكُلُ وَيَشْرَبُ»
